Deep core ionic photofragmentation of the CF,Cl, molecule
A.H.A. Gomes, W. Wolff, N. Ferreira, K.F. Alcantara, H. Luna,
G.M. Sigaud, A.C.F. Santos
> The photoionization of the CF,Cl, molecule has been studied around the Cl K edge. ® Photoion counts
yields for the fragmentation products have been recorded. ® The CF,Cl, undergoes a full break up
with the formation of doubly charged fragments. ® A relative site-selective fragmentation can be
observed

Mass spectrometric study on o(s)-alkyl
n,N-dimethylamino alkylphosphonates (alkyl-
phosphonothiolates) for Chemical Weapons
Convention verification purposes
Hamdollah Saeidian, Davood Ashrafi,
Mansour Sarabadani, Mohammad Taghi Naseri,
Mehran Babri
® Modified microsynthesis of O(S)-alkyl N.N-dimethylamino alkyl
phosphonates (alkylphosphonothiolates) which are included in schedule 2 of Chemical Weapons Convention (CWC) annex of chemicals, is reported. ® Theis
electron impact mass spectra with possible fragmentation routes are also investigated by MS/MS experiments, fragment ions of deuterated analogs and energy
calculations. ® These data could be useful for successful detection and identification the CWC-related chemicals in real sample or during OPCW proficiency tests

Electron ionization of NF,
M.A. Rahman, Sumona Gangopadhyay, Chetan Limbachiya,
K.N. Joshipura, E. Krishnakumar
> Partial and total electron impact ionization cross sections for NF, are measured
> Total scatterinagnd total ionization cross sections are also calculated. ® Measurements
differ considerably from previous measurements and present calculations. ® The
measured cross sections agree well with the “new” Deutsch-—Mark additiv ty rule
> The appearance potentials for various ions are measured, estimated and « mpared
